GENERAL

The Chromalox Type RBC-3 Radiant Heater is designed primar-

ily as an indoor comfort heater to be used where supplemental heat is

needed or for spot heating in unheated areas and damp locations.

Its aluminum construction and consequent light weight make it

ideal for suspension with the No. 2 size chain and “S” hooks pro-

vided. Aluminum reflector housing requires no painting and is eas-

ily cleaned.

WARNING: Users should install adequate controls

and safety devices with their electric heating

equipment. Where the consequences of failure may

be severe, back-up controls are essential.

Although the safety of the installation is the

responsibility of the user, Chromalox will be glad to

assist in making equipment recommendations.

WIRING

WARNING: Hazard of Electric Shock. Any installation

involving electric heaters must be effectively

grounded in accordance with the National Electrical

Code to eliminate shock hazard.

Electric wiring to heater must be installed in accordance with

the National Electrical Code and with local codes by a qualified

person. WARNING: Use copper conductors only.

WARNING: To prevent electrical wiring problems

due to overheating, route wiring conduit to avoid

contact with reflector housing.

MOUNTING

WARNING: Hazard of Electric Shock. Disconnect all

power before installing heater.

Minimum mounting distances for all heaters are as shown in

Figures A and B. Using the No. 2 size chain and “S” hooks fur-

nished, heaters are to be suspended in a horizontal position only.

NOTE: For proper balance, it is suggested that each of the four

corners be individually suspended (rather than gathered into a

common center mounting point, see Figure C and D).

OPERATION

WARNING: This heater is not intended for use in

hazardous atmospheres where flammable vapors,

gases, liquids or other combustible atmospheres

are present as defined in the National Electrical

Code. Failure to comply can result in explosion or

fire.

1. Minimum spacing from front of heater case to combustible

material is: 4 ft. — RBC3-12 (1200W)

7 ft. — RBC3-24 or RBC3-36 (2400W or 3600W)

2. Avoid temperatures in excess of 194˚F on nearby combustible

surfaces.

3. Do not operate heaters at voltages in excess of that stamped

on heater nameplate since excess voltage will shorten heater life.

4. CONTROLLING RADIANT INTENSITY —

When it is desirable to reduce radiant intensity, Input

Controllers may be used. These motor-driven cycling devices

can be used to vary heater output capacity from 4% to 100%.

Cycling devices are usually connected in holding coil circuit of

magnetic contactors. For further information regarding Input

Controllers and Contactors, see Chromalox catalog and/or con-

tact your local Chromalox representative.

5. WARNING: Because of the possibility of someone

unknowingly exposing the heater to combustible

hazards, the heater should not be left in operation

while unattended.

MAINTENANCE

WARNING: Hazard of Severe Shock. Disconnect all

power to heater before servicing these heaters.

A. Element Replacement (See Figure E)

1. Remove Terminal housing cover and gasket.

2. Disconnect element leads from external leads.

3. Loosen and disengage hex nut and washer from threaded fitting.

4. Pull element out of reflector housing and terminal box.

5. Slide new gasket (see Renewal Parts) onto threaded fitting of

replacement element. Note: Filler side of gasket faces away

from flange of threaded fitting. Insert new element through ter-

minal box opening, and slip on washer and hex nut before ele-

ment enters reflector housing. Tighten hex nut until element

mounting is secure.

6. Reconnect power supply leads to element terminals. Install

new terminal cover gasket (see Renewal Parts). Install terminal

box cover. Reconnect power to heater circuit.

B. Care of Reflector

The reflectors should be kept clean to obtain the maximum

radiant output. The entire assembly should be washed or brushed

off periodically to remove dust and dirt. However, if the inside of

the reflector gets badly soiled, a mild soap and water solution may

be used. Wipe reflecting surface dry to prevent permanent water

marks. For extreme cases of soil which do not yield to mild soap

cleaning, use plastic or fine steel wool type scouring pads com-

monly used on cooking utensils. Avoid use of ammonia or alka-

line cleaners which will etch the aluminum surfaces.

Note: Avoid hosing down the heater assembly because con-

duit may not be waterproof.
